A pulse generator circuit is an important building block for many electronic projects, such as the heart of a digital clock. Its purpose is basically to switch an output on and off for as long as the circuit is activated. Sometimes, these circuits…

A red, green, and blue (RGB) light-emitting diode (LED) is a useful electronic component that can produce visible light in a variety of colors. This is done by varying the intensity of the light output of the three different color LED elements (red,…

This project takes you through the steps to build, launch,and fly a paper airplane (glider) in sustained and controlled flight. Control in flight is achieved by modifying the wind the glider flies through with a large cardboard sheet or foam board…

This project takes you through the steps to build, launch, and fly an ultralight foam glider in sustained and controlled flight. Controlled flight is achieved by modifying the wind the glider flies through with a large cardboard sheet, or paddle.The…

In this project, you will build a small, vertical-axis wind turbine, or VAWT for short. VAWTs are not as efficient as their horizontal-axis cousins, but they are better suited to urban environments where wind can come from different…
